Answer:


A

Step-by-step explanation:

Here, we want to calculate the area of the semi-circle

To get this, we have to calculate the area of the circle and divide by 2

Mathematically, we have that as follows:


A\text{ = }(\pi r^2)/(2)

where pi is 3.14 and r which is the radius of the circle is 3.8 yd

Mathematically, we calculate the area as follows:


A\text{ = }(3.14*3.8^2)/(2)\text{ = 22.7 yd}^2
